High temperature absorption measurements were made for CO2 gas in Local Thermodynamic Equilibrium (LTE) with a hot cell and high resolution interferometer. The experimental data were compared to band-model and line-by-line model transmittance calculations using line parameters from the HITRAN and HITEMP data bases. The line-by-line calculations using HITEMP were in excellent agreement with experimental measurements, while the model calculations using the HITRAN data underpredicted the absorption by approx. 10%.
